Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671916, here are decompositions:

79 + 8671837 = 8671916
277 + 8671639 = 8671916
283 + 8671633 = 8671916
367 + 8671549 = 8671916
397 + 8671519 = 8671916
523 + 8671393 = 8671916
577 + 8671339 = 8671916
739 + 8671177 = 8671916

Showing the first eight; more decompositions exist.
